    drm: Hold mode_config.lock to prevent hotplug whilst setting up crtcs

    The fb_helper->connector_count is modified when a new connector is
    constructed following a hotplug event (e.g. DP-MST). This causes trouble
    for drm_setup_crtcs() and friends that assume that fb_helper is
    constant:

fixes this one, but https://intel-gfx-ci.01.org/CI/Patchwork_3189/ shows
another.
